blades your disappointed with

Gillette Silver Blues. They have been pretty much universally praised in all the forums. They're OK but not worth the money for me. The Gillette WS Indias are cheaper and better for me. The Nacets are much better.

Funny you'd mention that! I have one queued up for tomorrow morning's shave.  I haven't tried one yet.  We'll see what I think.
By the way, I love Nacets.

I'm not the most experienced guy here but at this point (and this could easily change), I've tried probably 8 or 9 different blades and the one that's elicited the most "Meh" reaction from me so far is the Voskhod. It was fine but certainly not the best blade I've used so far. But I have more of them in my quiver to try and I can change my mind.

Astra SS (not the Superior Platinum which is smooth and mild)

Well, a couple of GSB shaves under my belt now and I'm in agreement with you. OK but not great by any means.  And the Nacets are far superior for me.

Feather which just bite too much in an aggressive razor. 

Astra SP which are not sharp enough for me. 

Voshkod which can be dud loaded in a pack or box. 

Gillette Permasharp - just not smooth. 

Blades I never complain about - Nacet and Personna Platinums.  Sharp, smooth and just work for me.

I find that Voshkod blades can be a hit and miss sometimes. I had to give up on them after getting too many duds but will definitely have to revisit them again some day as I recently loaded up a Derby Extra in my Smart-Helix Apollo Light razor on plate II and it worked remarkably well for me and I had previously blacklisted these blades from my shaving routine a good 8 years ago at least.
I also feel like different blades in different razors with different angles works wonders but you gotta know what works and what doesn't.

I've had bad luck with Derby Extra's, the blades that came with dollar tree razor I had 3 duds in a row. On the vintage side, Gillette stainless I tried 2 from different lots and years ,and they were very rough.

I never really had expectations for any blades I purchased. I tested LOTS(!) of blades to separate the great that I would order again from the ones that could never make the cut. Only a handful made the cut and were reordered. The rest went to the wife where she is happily still using them years later.

Correction! I did buy some medical blades from an "alternate" online source for a decent price as a test but they were all duds. I did have hopes for them.

Each to their own. Different blades for different folks.  GSB is, and has now for several years, been my single most standard blade.  The only blade that I will use almost as frequently is the Seven O'Clock yellow.  A GSB simply works well for me and I've tried so many others.  And, fwiw, I've yet to get a good shave with a Nacet.  Tried Nacets again and again.  Never have worked.
